Question

Read the following statements:

(i) Mule is developed by interspecific hybridisation.
(ii) Groups of bees are called ‘swarms’.
(iii) For the herd-improvement cross-breeding is employed.
(iv) Bees are the pollinators of apple, Brassica, pear and sunflower.
(v) In MOET, the fertilised egg at 6–8 cell stage is recovered non-surgically.

• A. iii, iv, and v are false
• B. i, ii, and iv are true
• C. i, ii, iii and v are true
• D. i, ii, iii, and iv are true

Answer 1

The correct option is B i, ii, and iv are true

Statement (i)
Mule is produced by hybridisation of a male donkey with a female horse and hence it is an interspecific breeding.

Statement (ii)
Bees play an important role in the pollination of many flowering plants, and help in increasing the yield of certain plants such as sunflower, guava and strawberry. The group of bees are called swarms.

Statement (iv)
Bees are the pollinators of apple, Brassica, pear and sunflower.

Statement (iii)
MOET stands for Multiple ovulation and embryo transfer technology (MOET). MOET is required for herd improvement.

Statement (v)
In MOET, fertilised eggs at 8-32 cell stage are recovered non-surgically and transplanted into a surrogate mother for further development.

Final answer
c. i, ii, and iv are true.
